Base vector

AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Artifex jbig2dec versions prior to 0.18

Description The issue is related to a heap-based buffer overflow in the jbig2 image compose function of the jbig2 image.c component in the Jbig2dec decoder. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations For versions prior to 0.18, update to version 0.18 or later to resolve the issue. As a temporary workaround, consider restricting access to the jbig2 image compose function until a patch is available.
